We signed up for the "family meal" option (not a special diet or weight loss thing, just regular meal delivery) for two people during several weeks when our kitchen was being remodeled. I was expecting a step up from frozen microwavable dinners, honestly - boy, was I surprised. The food was fantastic, better than you'd get in many restaurants, and somehow prepared in a way that it was always delicious even heated in a microwave (which was all we had). Meat was never dry, veggies and fruits were very good quality, and I loved most of the default meal combos. On the few occasions when I don't like the menu plan, there are tons of other options to choose from, and I can make the switch easily online. If we have other plans for some nights, we can just cancel those meals and not pay for them (you have to cancel online with 48 hrs notice).
We ordered nightly dinners for two people, and at $40/day it's expensive, but the portions were generous. Meals were almost always enough for both of us to have lunch AND dinner, sometimes even more than that. It ended up being cheaper than ordering pizza or getting takeout all the time, and the food is much better. Plus they drop it off right outside your door overnight, very carefully packaged.
My only small complaint is that I tend to like spicy food, and they don't have a lot of that. Not to say it's bland - it's flavorful - but not a lot of heat.
The "family meal" plan would be a fantastic idea for anyone who 1) is remodeling a kitchen, like us, 2) works really long hours and wants beautiful food waiting for them at home with zero effort or 3) is in some stressful situation where cooking is difficult - taking care of a sick family member, for instance.
I think we're going to keep using this service for a night or two per week even when the kitchen's done. It's that good.
